23.3. Diagnostics of malfunctions of the transmission

(Malfunctions of other systems are also mentioned in this section, they are designated by a x symbol)

Noise in the transmission Noise decreases or disappears if to switch off coupling
Insufficient level of oil in a transmission case	Check level, if necessary add oil. Check whether there is no leak (see. "Oil leak", page 255). Clean сапун
Wear or damage of bearings, teeths of gear wheels	Replace worn-out bearings, gear wheels
Shaft of the transmission are displaced in the axial direction	Tighten nuts, replace the broken fixing details
Transfers join hardly, extraneous noises are absent
"x \Coupling is not switched off	See. "Diagnostics of malfunctions of coupling", page 253
Wear or deformation of the lever of gear shifting	Correct or replace the lever
Jamming of the spherical hinge of the lever of gear shifting	Replace faulty details, put LSTs-15 lubricant, LITOL-24 or ShRUS-4 in the hinge
Hardly rods of forks go (blocking crackers, agnails on rods, dirt in nests are jammed)	Clear the details which are worn out and deformed — replace
Hardly the sliding coupling on nave vents moves	Clear vents of dirt, cut agnails a file, replace details with the crumpled vents
Gear shifting forks are deformed	Replace forks
Transfers are spontaneously switched off
Springs of clamps lost elasticity, balls and/or nests of rods are worn-out	Replace worn-out details
Damage or wear of the blocking synchronizer rings	Replace rings
Damage or wear of teeths of the coupling or gear wreath of the synchronizer	Replace the coupling or a gear wheel
The synchronizer spring is broken	Replace a spring
Noise, crash, squeal of gear wheels at the time of transfer inclusion
"x \Coupling is switched off not completely	See. "Diagnostics of malfunctions of coupling", page 253
It is not enough oil in a transmission case	Add oil. Check whether there is no leak (see. "Oil leak" below). Clean or replace сапун
Wear or breakage of teeths of gear wheels and/or synchronizers	Replace details
Wear or deformation of a ring of the synchronizer of the included transfer	Replace a ring
Axial side play of shaft of the transmission	Tighten fastenings of bearings, replace worn-out bearings
Oil leak
Wear of epiploons	Replace epiploons.
Strong wear, zaboina on the condensed necks of shaft	Smooth out small damages a fine-grained skin and a zapoliruyta. Establishing a new epiploon, it is possible to nedopressovat a little it, without allowing a distortion (if necessary having enclosed under it remote laying up to 1 mm thick) that the edge of an epiploon worked by not worn-out part of a shaft. At considerable damages - replace shaft and epiploons
Elevated pressure in the transmission	Clean an opening of a main shaft of the Izh-2126 transmission or сапун VAZ-21074 transmissions
Fastenings of covers of a case of the transmission, coupling case weakened. Damage of laying	Tighten threaded connections. Replace laying (at their installation it is possible to use sealant)
Traffic jams are leaky wrapped	Tighten traffic jams (it is possible to put them on sealant)
